Display is ideal, there aren't any defects. I was disassembled my nokia, but all connections is good. I may suppose that can be a microdefect of a screen, but phone is working perfectly, touchpad also. And how you can see on the video, at first 3-4 seconds display are working perfectly and the going to the "matrix"
